Table 6. Reported MCID values of DASH, QuickDASH, and PRWE.

Author	Instrument	Total Subjects	Subjects Contributing to MCID	Diagnoses	Follow up Duration	MCID method	MCID	Additional Notes
Schmitt et al ⁽¹³⁾	DASH	211	44 minimally improved: 16 with diagnosis distal to elbow	Any upper extremity	3 months	Anchor based	13	MCID = 17 for diagnosis distal to elbow
Beaton et al⁽²¹⁾	DASH	200	172	Atraumatic: upper extremity	12 weeks	Statistical (MDC)^*	MDC 95%: 13
DASH Website: Summary analysis indicating minimal detectable change approximates MCID value for DASH with resultant MCID mean 13 (range, 8-17)
Current Study	DASH	102	29 minimally improved	Atraumatic: forearm to hand	24 weeks	Anchor based	10
Polson et al⁽¹⁵⁾	QuickDASH	35	15 much improved	Any upper extremity	up to 6 weeks	Anchor based	19	8 subjects minimally improved with mean QuickDASH change 13
Mintken et al⁽¹⁴⁾	QuickDASH	101	79 improved	Shoulder pain	mean 27 days	ROC Curve^**	8	Mean difference in QuickDASH score between stable and improved patients = 15
DASH Website: Summary analysis using minimal detectable change approximates MCID value for QuickDASH with resultant MCID mean 18 (range, 16-20)
Current Study	QuickDASH	102	29 minimally improved	Atraumatic: forearm to hand	2-4 weeks	Anchor based	14
Schmitt et al⁽¹³⁾	PRWE	211	16 minimally improved	Any upper extremity	3 months	Anchor based	24
Current Study	PRWE	102	29 minimally improved	Atraumatic: forearm to hand	2-4 weeks	Anchor based	14
